I-IEDDLE FOR LOOMS AND THE LIKE.

Application filed November 9, 1925.

My invention relates to a new and useful heddle for looms and the like, and it relates more particularly to heddles having two eyes through which there may be drawn two independent warp threads for the purpose of readily changing the 100mm weave double scale cloth, without the necessity of retying the harness as would otherwise be necessary to effect such a change.

The object of my invention is to provide a two scale heddle which may be used to weave either a single or a double scale fabric without the expense and loss of time of cutting down the harness and retying the same.

If at present, a harness employing the single eye heddles, known and used heretofore, is tied up to the jacquard, to weave a double scale fabric, that is, one in which a pair of warp threads are shed in unison at all times, and it is desiredto weave a single scale fabric with the harness thus tied up,

one half of the heddles would remain empty. These empty heddles are drawn up and down repeatedly by means of the harness cords and the jacquard hooks, without performing any function. WVith one half of the heddles or h-eddle eyes thus empty, there is always a possibility of putting the broken warp end in the wrong eye. Moreover, a working heddle has a tendency to wear outmuch more readily when no warp is drawn therethrough. Thus, if heretofore it was desired to eliminate the idle heddles, when changing from a double scale harness to a single scale harness, it was necessary to retie the harness entirely, at a considerable cost and expenditure of time.

I eliminate the above disadvantages of the heddles known and used heretofore, by my novel construction of double scale heddles, having a pair of eyes and also having a suitable vertical opening in the center of the heddles, through which may pass the alternate warp threads which are drawn through the succeeding heddles.

For the purpose of illustrating my invention, I have shown in the accompanying drawings forms thereof which are at present preferred by me, since they will give in practice, satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organi- Serial No. 67,831.

zation' of these instrumentalities as herein shown and described.

Referring to the drawing":-

Figure 1. represents a diagrammatic View in elevation, showing a series of jacquard hooks and corresponding jacquard needles well as the griff bars, and showing a harness tied to said jacquard hooks, embodying my invention.

Figure 2 represents a diagrammatic plan view showing the manner in which the warp threads are drawn through the eyes of one of the heddles, and through the slot in the succeeding heddle.

Figure 3 represents a front elevation of a,

hcddle of my novel construction, embodying my invention.

Figure {i represents an end elevation of the same.

Figure 5 represents a section on line 55 of Figure 3.

Referring to the drawings, in which, like reference characters indicate like parts, 1 designates a part of the jacquard frame, shown diagrammatically in Figure 1, in which 2, to 9 inclusive, represent a group of jacquard hooks controlled by the jacquard needles 10, 11, 12 and 13 in the well known manner. The jacquard cylinder is omitted from the drawings since the jacquard con struction is well known. 14, to 21 inclusive, designate the griff bars; alternate griff bars being carried by one gritf frame, while the other alternate griff bars are carried by another griff frame, in the particular modification shown in the drawings. In the par ticular illustration shown in the drawings,

each of the harness cords 22 to 25 inclusive, is connected to a pair of jacquard hooks. one of each of said pairs of hooks being adapted to be raised by a griff bar of one of said two griff frames. Each of the harness cords passes through a corresponding vertical opening in a comber board 26, for the purpose of spacing the lower ends of said cords, as is well known in the art. Each of the harness cords carries a heddle 27 of my novel construction, having an upper eyelet or opening 9.8 through which, the end of the harness cord is passed and tied, and having a lower eyelet 9.9 to which is attached the weight or lingoe, for the purpose of maintaining taut the heddle as well as the harness cords.

The heddle 27 of my novel construction, consists of a thin strip of suitable sheet metal, lnwing the two solid end portions 30 and 31, and the central slotted portion 32, in which is provided the longitudinal upright slot 33, as shown particularly in Figure 3. The two limbs 34. and 35 of the central slotted portion 32, of the heddle 27, are each provided with an eye 36 and 37 respectively, as shown in Figures 3, i and 5. Thus, with a warp thread drawn through each of the two eyes 36 and 3?, of each of the heddles shown in Figure l, and shown also diagramn'iat-ically in plan view in Figure 2, the warp thread passing through one of the eyes, as for instance, the eye 3'7, indicated in Figure 2, passes through the elongated slot 33 in the next suceeding heddle 27. This allows each warp to be shed by a separate eyeand at the same time permits the shedding of the warp threads without any interference with each other, as they are shifted, since the slots guide the warp threads as they are being shifted. As shown in Figures 3, at and 5, the limbs and 35 are spread apart as shown particularly in Figures 4 and 5. Similarly, the two sides of each of the eyes 36 and 37 are also spread apart.

By the employment of heddles of my novel construction, each warp is shed by an independent eye, thus eliminating any twisting of the two warp threads, as is the case when said warp "threads are drawn through a single eye, that is, when shed by a single scale heddle of the usual construction. Thus, with the use of heddles of my novel construction, a harness may readily be changed from a double to a single scale, and vice versa, by merely employing one or both eyes respectively of each of the heddles. hen weaving a single scale fabric with heddles of my novel construction, either the odd or the even eyes of the heddles may be utilized for drawing the warp threads therethrough, and in such event the danger of passing broken warp threads through the wrong eye is practically eliminated. In weaving a double scale fabric, I eliminate one half of the number of heddles.

It will now be apparent that I have devised a novel and useful construction in heddles for looms and the like which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described a preferred embodiment thereof which will give in practice satisfactory and reliable results, it is to be understood that such embodiment is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A heddle of the character stated, comprising an elongated body portion of thin sheet metal and of unitary structure, a terminal eyelet at each end thereof, a central longitudinal slot intermediate of the ends thereof and an elongated eye upon each side of said slot and located substantially midway of the length thereof, through which a warp may be drawn.

2. A heddle of the character stated, comprising an elongated body of thin sheet metal, terminal eyelets in each of the ends thereof, a longitudinal slot extending a portion of the length thereof, separating the body portion into two limbs, and an eye in each of said limbs substantially centrally of the length of said slot, said limbs being also spaced apart from each other in two spaced parallel planes.

A heddle of the character stated, comprising an elongated, unitary and integral plate having an elongated, longitudinal slot therein, intermediate of its ends, thereby forming a pair of limbs adjacent said slot, each of said limbs having an eyelet extending therethrough.

a. A heddle of the character stated, comprising an elongated unitary and integral plate having an elongated longitudinal slot therein, intermediate of its ends, thereby forming a pair of ofl'set limbs adjacent said slot; each of said limbs having an elongated eyelet therein with offset longitudinal walls.

5. A heddle of the character stated, comprising an elongated, unitary and integral plate having an elongated, longitudinal and substantially medium slot therein, intermediate of its ends, thereby forming a pair of limbs adjacent said slot; each of said limbs having an eyelet extending therethrough, and a terminal eyelet in each end of said elongated plate.

6. A heddle of the character stated, comprising an elongated unitary and integral plate having an elongated longitudinal slot therein, intermediate of its ends, thereby forming a pair of offset limbs adjacent said slot; each of said limbs having an elongated eyelet therein with offset longitudinal walls, and a terminal eyelet in each end of said elongated plate.

In testimony whereof I have hereunto signed my name.
